How to change the boot screen in the assembly?

[telindus]

I tried as described in the manuals Lubuntu:

 

1)sudo apt-get update

2) sudo apt-get install plymouth-theme-*

3) sudo update-alternatives --config default.plymouth

4) sudo update-initramfs -u 

 

As a result, all the same boot black console rather than graphical theme. Please help us understand how to make the graphics theme at startup and reboot.

Hi!

 

Guys I am a complete noob in this case. All that I found on the internet I pereprobyval, but nothing helps. I was like a black screen to boot, and remains.

 

Hardware: cubieboard-2 + http://www.waveshare.com/product/7inch-Capacitive-Touch-LCD-D.хтмл

 

Software - Linux cubieboard2 3.4.107-cubieboard2 # 14 SMP PREEMPT Tue Jun 9 13:06:06 ALMT 2015 armv7l armv7l armv7l GNU / Linux

 

At check of the demon plymouth - it works (after boot, you can run it and it will show the topic I asked, but for some reason - only on the display that I prescribe With X-server and LSD did not work).

 

Prompt where to "dig" to work?

I play with this some time ago and all I can remember is that plymouth is a waste of time. Since you are working with LCD, you get access when the driver, present in kernel, is loaded. I doubt (but possible) it's supported in uboot. If you have it in uboot, you can use our scripts - we are showing Armbian boot logo on (some) A10/A20 builds. Logo pop ups early in the boot stage, but when FB is initialized in kernel it gets overwritten.

However, what you are trying to achieve is probably not done yet so you are not facing a trivial task.

I cube is not boot has a black screen. But when connecting HDMI I see the beginning of the boot, the boot is why he takes the wrong port (LVDS)? And how to fix it? (Video boot - https://youtu.be/IaT7RuKYJ-0)

 

 

Regardin gplymouth:

1) It is not prescribe echo 'FRAMEBUFFER = Y' >> /etc/initramfs-tools/initramfs.Ñonf + update-initramfs y. Not loaded plymouth in initratfs.

Check lsinitramfs -l /boot/initrd.img-3.4.107-cubieboard2 | grep plymouth - shows that his plymouth and Themes download.

2) in the script there is a demand plymouth PREREQ = "framebuffer console_setup brltty" - put brltty install and update-initramfs y .. I checked it was loaded in /boot/initrd.img-3.4.107-cubieboard2.

3) blacklist-framebuffer.conf Files., Fbdev-blacklist.conf. - Renamed .bak

4) Now download commands from the framebuffer file

copy_modules_dir kernel / drivers / char / agp

copy_modules_dir kernel / drivers / gpu

 

Work (ie in /boot/initrd.img-3.4.107-cubieboard2 -. There were those files). But loading modules

manual_add_modules fbcon

manual_add_modules vesafb

manual_add_modules vga16fb

 

Does not work.

Appropriately when attempts to point(splash) to boot.cmd(mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr) command causes the condition "brick". I do not know where to look further, to make it work. Who else have any ideas?

Do I understand you correct that:
Your LCD capacitive touchscreen works - you can control the device (A20 SBC) from the screen?
 

Please help us understand how to make the graphics theme at startup and reboot.

What you would like to have on the LCD is a Logo /Animation while booting and again on shutdown of the SBC?

[telindus]

1)Your LCD capacitive touchscreen works - you can control the device (A20 SBC) from the screen?

Yes.

 

2) What you would like to have on the LCD is a Logo /Animation while booting and again on shutdown of the SBC?

I will approach will work if the default themes (there will be a device that is boot).Either Custom Image (I tried to register in init.d script containing command - /usr/bin/fbi -T 1 -noverbose -a /etc/splash.png) - but this picture is shown at the very end of the boot for 5-10 seconds . That does not solve the problem of black screen during boot.

To get logo early in boot you need to work with uboot: (just like they did in your video) or booting armbian:

 

Check my patch:

https://github.com/igorpecovnik/lib/blob/master/patch/u-boot/u-boot-default/sunxi-boot-splash.patch.disabled

You need to rework it since you probably want to lock u-boot down and boot without messages.

 

It's currently disabled since it breaks sun8i compilation. This does not solve shutdown logo, but that can be done with some bash script and fbi.

 

I don't think there is any "apt-get install" solution available.

[telindus]

Igor,

 

I agree on any logo at boot time (better if it is animated), but there are two problems which I'm trying to solve:

1) Prior to full load Linux - the screen is black LSD. Using the script in init.d and fbi gives only at the end of the download wallpaper for 5-10 seconds.

2) Why is that as you can see in the video message download (text, logo) can be seen only through HDMI.

 

I do not understand what to do with the patch.

[Igor]

1. Yes, it's normal. You can't use LCD before loading it's driver.

2. Because your U-boot is configured to display to HDMI by default. If you want to use an LCD, you need a driver for it within U-boot. 

 

The problem is fairly complex and I also don't have much experiences in this area to give you better guidance.

[Tido]

@telindus

To which Connector did you attach the LCD to the SBC?

 

Did you read in the A20 manual how to address this /your output first?

[telindus]

@Igor,

but how do you know which driver is using Linux? Can get it through initramfs-tools to load?

 

@Tido,

40 pin connector.

I did not find in the manual that the A20 or on the subject.
